最近刚买了自己的vps,今天关注了vps需要注意的点,结果发现vps非常需要注意安全,作为一个直接暴露在互联网上的主机,如果只有root+密码的模式,那么非常容易被暴力破解。如果被破解了,那么黑客就可以使用你的vps刷流量(流量超标需要你来付钱!)、发动DDOS攻击等。
首先说明一下,我的vps是CentOS,一开始我也是以为作为一个个人的博客站,即没有什么信息,也没有什么隐私,应该没有什么问题。结果今天看了一下安全日志:
vim /etc/log/secure
被一堆ip的密码错误,登录失败等刷屏
试图破解我root密码的ip足足有185个,也就是说同时有185台设备在试图暴力破解我的root密码,黑名单是使用denyhosts来抓取的,附录是试图破解我root密码的ip黑名单,我查了其中一个ip,香港的地址- -
黑名单的判断口径是试错10次root密码,因此判断绝对不会有错!由此可见公网上有多么的恐怖。
下面我总结一下公网上保护自己的经验:
三道安全门
一、修改ssh登陆的默认端口
为什么要修改默认端口?一般新手都会使用默认端口,而使用暴力破解法的人必定会优先在默认端口试错,而修改端口之后,这些黑客们就必须同时使用正确的端口与密码。平均试错次数至少增加了1000倍有余吧。
打开配置文件:
[[email protected] ~]# vim /etc/ssh/sshd_config
修改默认端口,端口项默认是是被注释掉的,其默认值是22,修改后如下:
(假设我们修改为64851,修改后的端口你自己一定得记住,不然自己也没办法登陆了)
Port 64851
修改完之后重启sshd
[[email protected] ~]# /etc/init.d/sshd restart
二、使用denyhosts
使用denyhosts的好处在于它能够在极大程度上减缓暴力试错的速度,本来暴力试错的黑客使用200台电脑同时进行试错,那么他成功暴力破解的时间就会降低200倍。而如果有了denyhosts,每个ip试错超过一定次数(可以自己设置,假设这里次数是10)之后就不再允许继续试错,那么暴力试错者在每台电脑尝试了10次之后就只能换电脑了,如此基本上等价于杜绝了它破解密码的可能性。
1、安装配置denyhosts:
[[email protected] ~]# yum install denyhosts
这里需要确认是否安装成功,比如说,我用的DigitalOcean上512M的电脑,内存不怎么够用,因为内存不够安装失败了,因为http服务器缓存占了不少内存。最后我重启电脑之后立即安装denyhosts成功。
2、修改配置文件
[[email protected] ~]# vim /etc/denyhosts.conf
配置文件修改结果可以参考:
SECURE_LOG = /var/log/auth.log HOSTS_DENY = /etc/hosts.deny PURGE_DENY = 1w BLOCK_SERVICE = sshd DENY_THRESHOLD_INVALID = 5 DENY_THRESHOLD_VALID = 10 DENY_THRESHOLD_ROOT = 10 DENY_THRESHOLD_RESTRICTED = 1 WORK_DIR = /var/lib/denyhosts SUSPICIOUS_LOGIN_REPORT_ALLOWED_HOSTS=YES HOSTNAME_LOOKUP=YES LOCK_FILE = /var/run/denyhosts.pid ADMIN_EMAIL = [email protected] SMTP_HOST = localhost SMTP_PORT = 25 SMTP_FROM = DenyHosts<[email protected]> SMTP_SUBJECT = DenyHosts Report AGE_RESET_VALID=5d AGE_RESET_ROOT=25d AGE_RESET_RESTRICTED=25d AGE_RESET_INVALID=10d RESET_ON_SUCCESS = yes DAEMON_LOG = /var/log/denyhosts DAEMON_SLEEP = 30s DAEMON_PURGE = 1h
三、使用RSA密钥
随便找一台Linux设备(Unix家族的系统应该都可以、除此之外,windows的mingw也是可以的),使用如下指令:
[[email protected] ~]# ssh-keygen -t rsa
然后根据提示输入目录与密码
1、目录如果不填写(直接按Enter键则为空),那么id_rsa会存在 ~/.ssh/目录下;
2、密码的含义是即便你密钥对了,还得再验证一次密码。密码一般不填写,因为密钥的安全性已经很高了,如需加强保密级别,可以填写密码。
生成的两个密钥:
-rw------- 1 root root 1675 Apr 21 13:20id_rsa -rw-r--r-- 1 root root 394 Apr 21 13:20 id_rsa.pub
其中id_rsa.pub是公钥,id_rsa是私钥,私钥需要自己保存(用于登陆vps)
生成密钥之后,将公钥复制到~/.ssh/目录下,然后修改sshd的配置文件:
[[email protected] ~]# vim /etc/ssh/sshd_config
修改如下参数:
RSAAuthentication yes #RSA认证 PubkeyAuthentication yes #开启公钥验证 AuthorizedKeysFile .ssh/authorized_keys #验证文件路径 PasswordAuthentication no #禁止密码认证 UsePAM no #禁用PAM
修改完之后重启sshd服务:
[[email protected] ~]# /etc/init.d/sshd restart
3、修改secureCRT参数,使用密钥登陆服务器
进入Session Options界面,选中SSH2-PublicKey-Properties,如图
选中Properties之后会进入下一个界面,如图:
在Use identity or certificate file栏填写自己的私钥id_rsa所在的目录(我的私钥名字是zy)。
最后
设置完以上配置之后,你的vps被暴力破解的概率基本等于0啦。而你也可以正常的使用vps了。
